Abstract:
The robot welding control is studied for the weld groove of thrust chamber outer wall. Based on the acquired groove parameters with the active laser sensor, the adaptive welding for thrust chamber outer wall is achieved and the welding quality for thrust chamber is guaranteed by building the models of groove,parameter and welding. On the basis of “static” studies,the “dynamic” control of the process parameters is studied and an adaptive welding parameter model is established for the groove of outer wall in thrust chamber. Furthermore,the welding adaptive control system is established combined with the fuzzy control algorithm and the welding experiment is accomplished for a thrust chamber simula-tor, which verified the applicability of model and the adaptive welding system. A parameter calculation model of hot wire TIG welding is established for the materials such as S-06 and 1Cr21Ni5Tiin the thrust chamber of liquid rocket engine, which can cover the thrust chamber joint with a depth of 5～12mm. The adjustment factor of the welding adaptive control system is optimized for the control response speed under the SIMULINK platform. The welds of the test joint are well welded, which passes the X-ray examination, and the strength is higher than 90% of the base metal.
